[2] Therefore, the possibility of successful termination of tachycardias with pacing can be anticipated on the basis of the mechanism. It is therefore useful to consider the origin of ventricular ...

The major distinguishing feature of a biventricular pacemaker is the insertion of a left ventricular lead to accomplish left ventricular pacing, in addition to the right ventricular lead for right ...

In single-chamber pacing systems, a pacing lead is placed in the ventricle or the atrium. Single-chamber ventricular pacing systems usually employ a lead placed in the right ventricular apex and ...

this study found that only 4 of 25 patients who were mapped during the procedure experienced heart block that required a permanent pacemaker. This was a promising finding because ventricular ...

This means the ventricular rate (QRS complexes ... medications), the rhythm is usually irreversible and a permanent pacemaker is indicated.

The new standard of care in pacing is to reduce unnecessary right ventricular pacing to as close to zero as possible. Mounting evidence suggests that right ventricular pacing is associated with a ...
